Speed has always been essential to Motorhead's music. The metal band's fans better show off some quickness of their own if they want to snatch up one of the very limited-edition 'Motor-Bag' collectibles that are available now.

Limited to 4,000 copies, each Motor-Bag package ($99) comes in, obviously, a bag — a black messenger-style carrier emblazoned with the Motorhead logo. Inside, you'll find two double-vinyl concert albums by leader Lemmy Kilmister and company, both recorded during the band's "The World Is Yours" tour — one is the Nov. 16, 2010, show in Manchester, England, and the other is the Feb. 28, 2011, gig in New York City.

But wait, there's more: a laminated pass, plus a mounted, numbered chunk of the backdrop Motorhead used on its 2010-11 concert trek.

Speaking of concerts: Motorhead's North American tour with Megadeth continues tonight (Jan. 27) in Connecticut and wraps up Feb. 28 in Colorado.
